Full Description

This part of IEC 62271, which is a Technical Specification, is applicable to alternating currentcircuit-breakers with intentional non-simultaneous pole operation designed for indoor or outdoorinstallations and for operation at frequencies of 50 Hz and 60 Hz on systems having voltagesabove 1 000 V. This document provides additional ratings and type tests to be conducted forthis type of circuit-breaker and is intended to be used in conjunction with IEC 62271-100:2021.Intentional non-simultaneous pole operation can be implemented by mechanical or electricalmeans and both methods are within the scope of this document.

Satisfactory service performance of controlled switching systems is influenced by the inherentperformance capabilities of the switching device and by the choice of a suitable controller (relay)and requires proper integration of these devices. Consequently, practical applications ofcontrolled switching require a coordinated approach to system integration.

This document addresses the performance capabilities of the switching device and establishessuitability for controlled switching when applied with an appropriate controller. Type tests aredefined, and guidance is provided to establish the switching device capabilities and parametersrequired to facilitate proper system integration, but this document does not address theperformance requirements of the controller. In summary, compliance and testing in accordancewith the requirements and guidance presented herein verify the ability of the switching deviceto meet defined switching accuracy requirements only when applied with a suitably specifiedcontroller.
